Description

VERDICHTER MIT EINSATZSTÜCK IM EINLASSBEREICH  COMPRESSOR WITH INSERT IN THE ENTRANCE AREA
Die vorliegende Erfindung betrifft eine Verdichteranordnung gemäß dem Oberbegriff von Anspruch 1. Des Weiteren betrifft die Erfindung ein Verfahren zur Herstellung einer solchen gemäß dem Oberbegriff von Anspruch 13. The present invention relates to a compressor assembly according to the preamble of claim 1. Furthermore, the invention relates to a method for producing such according to the preamble of claim 13.
Auf dem Gebiet der Verdichter von Turboladern, insbesondere Abgasturboladern, sind verschiedene Maßnahmen zur Kennfeldstabilisierung bekannt. Eine Möglichkeit zur Stabilisierung zeigt z.B. die Druckschrift CH 675 279 A5, wobei mittels eines Stabilisierungsringes und einer Ausnehmung bzw. Luftspaltes in Form einer ringförmigen Nut eine Kennfelderweiterung erreicht wird. Eine weitere Anordnung ist z.B. aus der DE 40 27 174 C2 bekannt, wobei ein Einlaufring zusätzlich die Strömungsverhältnisse günstig beeinflusst. In the field of compressors of turbochargers, in particular exhaust gas turbochargers, various measures for map stabilization are known. One way of stabilizing shows e.g. the publication CH 675 279 A5, wherein by means of a stabilizing ring and a recess or air gap in the form of an annular groove a map extension is achieved. Another arrangement is e.g. known from DE 40 27 174 C2, wherein an inlet ring additionally influences the flow conditions low.
Bei derartigen Vorrichtungen zur Kennfeldstabilisierung kann es vorkommen, dass bei einer Luftströmung durch den Spalt zur Kennfeldstabilisierung um das Verdichterrad, in Abhängigkeit der Laderdrehzahl des Turboladers bzw. des Verdichterrads für das menschliche Gehör unangenehme Frequenzen, zum Beispiel zwischen 14khz und 17khz, erzeugt werden. Deckt man den Querschnitt, z.B. den Ringquerschnitt des Spalts, um das Verdichterrad so ab, dass kein Schall in das zuführende Rohr geleitet wird, werden die hohen Frequenzen deutlich verringert. Dazu werden im Stand der Technik zum Beispiel separate Teile für eine akustische Abschirmung verwendet, z.B. Blechprofile oder Drehteile, welche z.B. über Sprengringe gehalten werden, direkt eingepresst oder anderweitig befestigt sind. Diese bekannten Lösungen sind aufwändig in der Herstellung, erfordern mitunter mehrere Montageschritte und sind kostenintensiv. In such devices for map stabilization, it may happen that at an air flow through the gap for map stabilization to the compressor wheel, depending on the supercharger speed of the turbocharger or the compressor wheel for human hearing unpleasant frequencies, for example between 14khz and 17khz generated. If one covers the cross-section, e.g. the annular cross section of the gap around the compressor wheel so that no sound is conducted into the feeding tube, the high frequencies are significantly reduced. For this purpose, for example, separate parts for acoustic shielding are used in the prior art, e.g. Sheet metal profiles or turned parts, which are e.g. held by snap rings, directly pressed or otherwise secured. These known solutions are expensive to produce, sometimes require several assembly steps and are costly.

Fig. 1 zeigt exemplarisch Bestandteile einer erfindungsgemäßen Verdichteranordnung 1 , wobei die Verdichteranordnung 1 noch nicht zusammengefügt ist. Die Verdichteranordnung 1 besteht z.B. aus einem Verdichtergehäuse 2, welches mit einem Rohrabschnitt 3 und weiterhin zum Beispiel mit einem Ansaugrohr 4 verbindbar ist. FIG. 1 shows by way of example components of a compressor arrangement 1 according to the invention, wherein the compressor arrangement 1 has not yet been assembled. The compressor assembly 1 consists e.g. from a compressor housing 2, which is connectable to a pipe section 3 and further, for example, with an intake pipe 4.
Die Verdichteranordnung 1 ist zur Verwendung in einem Turbolader vorgesehen, z.B. einem Abgasturbolader einer Brennkraftmaschine bzw. eines Verbrennungsmotors, z.B. eines V-Motors. Bei einer derartigen bekannten Anordnung wird ein Verdichterrad (nicht dargestellt) von einem auf der Antriebswelle des Verdichterrads drehfest montierten Turbinenrad angetrieben, um die Förderung von Frischluft zur Leistungssteigerung des Motors infolge der Drehung des Verdichterrads zu verstärken. The compressor assembly 1 is intended for use in a turbocharger, e.g. an exhaust gas turbocharger of an internal combustion engine or an internal combustion engine, e.g. a V-engine. In such a known arrangement, a compressor wheel (not shown) is driven by a turbine wheel rotatably mounted on the drive shaft of the compressor wheel to enhance the delivery of fresh air to increase the power of the engine due to the rotation of the compressor wheel.
Die erfindungsgemäße Verdichteranordnung 1 weist ein Gehäuse bzw. ein Verdichtergehäuse 2 auf, in welchem z.B. die Anordnung eines Verdichterrads vorgesehen ist. Zur Anströmung, z.B. mit Frischluft bzw. Förderluft (Ladeluft), in einer Anströmrichtung 5 (Pfeil Fig. 1 ) ist eine erste Einlassöffnung 6 mit einem ersten Querschnitt 7 sowie eine zweite Einlassöffnung 8 mit einem zweiten Querschnitt 9 vorgesehen. Erste 6 und zweite 8 Einlassöffnung sind z.B., bezo- gen auf die Strömungsrichtung bzw. eine Mittelachse A des Verdichtergehäuses 2, radial zueinander benachbart angeordnet, d.h. in Richtung einer Senkrechten auf die Mittelachse A zueinander versetzt angeordnet. Insbesondere liegt z.B. die zweite Einlassöffnung 8 radial näher an einer Mittelachse A als die erste Einlassöffnung 6. The compressor assembly 1 according to the invention comprises a housing or a compressor housing 2, in which, for example, the arrangement of a compressor wheel is provided. For flow, for example, with fresh air or conveying air (charge air), in a direction of flow 5 (arrow Fig. 1), a first inlet opening 6 is provided with a first cross section 7 and a second inlet opening 8 with a second cross section 9. First 6 and second 8 inlet openings are, for example, gene to the flow direction or a central axis A of the compressor housing 2, arranged radially adjacent to each other, that is offset from each other in the direction of a perpendicular to the central axis A. In particular, for example, the second inlet opening 8 is located radially closer to a central axis A than the first inlet opening 6.
Die erste Einlassöffnung 6 dient der Ausbildung einer Luftströmung in einem kennfeldstabilisierenden Spalt 10 bzw. einem kennfeldstabilisierdem Kanal, welcher als kennfeldstabilisierende Maßnahme (KSM) um ein Verdichterrad vorgesehen ist. Die Einlassöffnung 6 kann dabei segmentiert sein, z.B. durch (radial verlaufende) Stege 1 1 unterbrochen sein (z.B. Fig 3). Die erste Einlassöffnung 6 ist z.B. ringförmig, z.B. kreisringförmig, ausgebildet bzw. weist einen ringförmigen Querschnitt 7 auf, welcher zum Beispiel in radialer Richtung um den zweiten Querschnitt 9 herum angeordnet ist, z.B. konzentrisch angeordnet ist. Der Querschnitt 7 wird dabei z.B. durch die Fläche der Ringform gebildet. The first inlet opening 6 serves for the formation of an air flow in a map-stabilizing gap 10 or a map-stabilizing channel, which is provided as map-stabilizing measure (KSM) around a compressor wheel. The inlet opening 6 may be segmented, e.g. be interrupted by (radially extending) webs 1 1 (for example, Figure 3). The first inlet port 6 is e.g. annular, e.g. annular, formed or has an annular cross-section 7, which is arranged for example in the radial direction around the second cross-section 9 around, for. is arranged concentrically. The cross section 7 is in this case e.g. formed by the surface of the ring shape.
Die zweite Einlassöffnung 8 dient zur Anströmung des Kanals 12, in welchem z.B. die Anordnung des Verdichterrads und z.B. die Ausbildung der dieses anströmenden Hauptströmung vorgesehen ist. Die zweite Einlassöffnung 8 weist zum Beispiel einen kreisförmigen Querschnitt auf und ist z.B. konzentrisch zu der ersten Einlassöffnung 6 innerhalb deren Innenumfangs angeordnet. The second inlet opening 8 serves for the flow of the channel 12, in which e.g. the arrangement of the compressor wheel and e.g. the formation of this inflowing main flow is provided. The second inlet opening 8 has, for example, a circular cross-section and is e.g. arranged concentrically with the first inlet opening 6 within its inner circumference.
Die erste 6 und zweite 8 Einlassöffnung werden zum Beispiel durch ein konzentrisch zu diesen angeordnetes, in axialer Richtung verlaufendes Stegelement bzw. Wandelement 11 a bzw. das Verdichtergehäuse 2 gebildet, wobei erste 6 und zweite 8 Einlassöffnung z.B. strömungsmäßig im Einlaufbereich der Anströmung verbunden sind. The first 6 and second 8 inlet openings are formed, for example, by an axially extending web element 11 a or the compressor housing 2, wherein first 6 and second 8 inlet openings e.g. are fluidly connected in the inlet region of the flow.
Zur Befestigung bzw. Verbindung mit einem erfindungsgemäßen (Verbin- dungs-)Rohrelement bzw. Rohrabschnitt 3, welcher z.B. als Steckrohr (i.e. zur Steckverbindung) ausgebildet ist, weist das Verdichtergehäuse 2 weiterhin zum Beispiel ein Verbindungselement 13 auf, z.B. eine Aufnahme 14 in Form eines ringförmigen Flanschelements 15 (Ringflansch), welches zum Beispiel zur Aufnahme eines Endes des einsteckbaren Rohrabschnitts 3 ausgebildet ist. For fastening or connection with a (connecting) pipe element or pipe section 3 according to the invention, which e.g. is designed as a plug-in tube (i.e., the plug connection), the compressor housing 2 further comprises, for example, a connecting element 13, e.g. a receptacle 14 in the form of an annular flange member 15 (annular flange), which is designed for receiving one end of the plug-in pipe section 3, for example.
Daneben könnte das Verbindungselement 13 bzw. die Aufnahme 14 z.B. in Form einer Ringnut im Verdichtergehäuse 2 ausgebildet sein. Das in Fig. 1 gezeigte Verbindungselement 13 in Form einer Aufnahme 14, umfängt zum Bei- spiel die erste 6 und zweite 8 Einlassöffnung in radialer Richtung und ist diesen z.B. in axialer Richtung vorgelagert, um z.B. ein Ende eines darin aufgenommenen Rohrabschnitts 3 zu führen bzw. zu haltern. In addition, the connecting element 13 or the receptacle 14 could be formed, for example, in the form of an annular groove in the compressor housing 2. The connecting element 13 shown in FIG. 1 in the form of a receptacle 14 encloses, for example, play the first 6 and second 8 inlet opening in the radial direction and this example upstream in the axial direction, for example, to lead or support one end of a pipe section 3 received therein.
Die Verbindung mit dem Rohrabschnitt 3 ist vorzugsweise eine Steckverbindung, z.B. eine dauerhafte, ohne zerstörerischen Eingriff lösbare Steckverbindung, welche mit geringem Aufwand realisierbar ist. Die Verbindung könnte als kraftschlüssige, formschlüssige oder sogar stoffschlüssige Verbindung sowie als Kombination derartiger Verbindungen ausgebildet sein. Das Verbindungselement 13 bzw. die Aufnahme 14 weist zum Beispiel einen Innendurchmesser 16 auf, der einem Aussendurchmesser 17 eines aufzunehmenden Rohrabschnitts 3 angepasst ist, insbesondere derart, dass sich zwischen Verbindungselement 13 und Rohrabschnitt 3 eine Klemmkraft im Falle einer Verbindung einstellt, i.e. einer Anordnung des Rohrabschnitts 3 an dem Verdichtergehäuse 2. Der Rohrabschnitt 3 ist dabei zur Anordnung an jener Verdichtergehäuseseite vorgesehen, welche die erste 6 und zweite 8 Einlassöffnung aufweist (Anströmseite). The connection to the pipe section 3 is preferably a plug connection, e.g. a permanent, without destructive interference releasable connector, which is feasible with little effort. The connection could be designed as a frictional, positive or even cohesive connection and as a combination of such compounds. The connecting element 13 or the receptacle 14 has, for example, an inner diameter 16 which is adapted to an outer diameter 17 of a male pipe section 3, in particular such that between the connecting element 13 and the pipe section 3 a clamping force is established in the case of a connection, i.e. an arrangement of the pipe section 3 on the compressor housing 2. The pipe section 3 is provided for arrangement on that compressor housing side, which has the first 6 and second 8 inlet opening (upstream side).
Die erfindungsgemäße Verdichteranordnung 1 weist einen Rohrabschnitt 3 auf, welcher zum Beispiel ein Ansaugrohr 4 ist, insbesondere jedoch ein von einem Ansaugrohr 4 verschiedener Rohrabschnitt 3 ist. Der Rohrabschnitt 3, welcher zum Beispiel hülsenförmig gebildet ist, weist ein erstes Ende 18 auf, welches bei Verbindung mit dem Verdichtergehäuse 2 bzw. dessen Verbindungselement 13 z.B. der ersten 6 und zweiten 8 Einlassöffnung bzw. deren Querschnitten in axialer Richtung gegenüberliegt, sowie ein zweites Ende 19, welches als Ansaugrohrende ausgebildet ist oder vorzugsweise zur Verbindung mit einem verdichterseitigen Ansaugrohrende 20 eines Ansaugrohres 4 ausgebildet ist. The compressor assembly 1 according to the invention has a pipe section 3 which, for example, is an intake pipe 4, but in particular is a pipe section 3 different from an intake pipe 4. The pipe section 3, which is sleeve-shaped, for example, has a first end 18 which, when connected to the compressor housing 2 or its connecting element 13, is e.g. the first 6 and second 8 inlet opening or their cross-sections in the axial direction opposite, and a second end 19 which is formed as Ansaugrohrende or preferably for connection to a compressor-side intake pipe end 20 of an intake pipe 4 is formed.
Der Rohrabschnitt 3 weist z.B. einen Kanal, insbesondere einen innenliegenden bzw. Innenkanal 21 auf, welcher im Wesentlichen einen ersten Querschnitt 22 aufweist, wobei der Querschnitt 22 bei Anordnung des Rohrabschnitts 3 an dem Verdichtergehäuse 2 dem Querschnitt 9 bzw. der zweiten Einlassöffnung 8 z.B. in axialer Richtung gegenüberliegt und z.B. dem Durchmesser bzw. Querschnitt der zweiten Einlassöffnung 8 angeglichen ist. Die Querschnitte des Innenkanals 21 sowie der zweiten Einlassöffnung 8 korrespondieren insofern miteinander. Die sich derart gegenüberliegenden Quer- schnitte 22, 9 ermöglichen, dass sich ein Strömungskanal gleichen Querschnitts aus dem Innenkanal 21 des Rohrabschnitt 3, der zweiten Einlassöffnung 8 sowie dem Kanal 12 bilden lässt. The pipe section 3 has, for example, a channel, in particular an inner or inner channel 21, which essentially has a first cross section 22, wherein the cross section 22 in the arrangement of the pipe section 3 on the compressor housing 2 the cross section 9 and the second inlet port 8, for example in Opposite axial direction and, for example, the diameter or cross section of the second inlet port 8 is aligned. The cross sections of the inner channel 21 and the second inlet opening 8 correspond to one another in this respect. The opposing cross-section Sections 22, 9 allow that a flow channel of the same cross-section from the inner channel 21 of the pipe section 3, the second inlet port 8 and the channel 12 can be formed.
Das erste Ende 18 des Rohrabschnitts 3 ist darüber hinaus insbesondere zur Erzielung einer erfindungsgemäßen Abdeckung, zumindest einer Teilabdeckung, der ersten Einlassöffnung 6 bzw. des ersten Querschnitts 7 in radialer Richtung ausgebildet, insbesondere bei Anordnung an dem Verdichtergehäuse 2. Durch den Rohrabschnitt 3, welcher z.B. als Steckrohr ausgebildet ist, wird der erste, z.B. ringförmige, Querschnitt 7 in radialer Richtung abgedeckt, insbesondere um den Strömungsquerschnitt abgedeckt, z.B. vollständig in radialer Richtung abgedeckt. Eine akustische Abschirmung wird somit erreicht, die eine Rückleitung störender Frequenzen, z.B. im Bereich zwischen 14 kHz und 17 kHz, in das Ansaugrohr 4 unterdrückt, zumindest deutlich verringert. The first end 18 of the pipe section 3 is also formed in particular to achieve a cover according to the invention, at least a partial cover, the first inlet port 6 and the first cross section 7 in the radial direction, in particular when arranged on the compressor housing 2. By the pipe section 3, which eg is designed as a plug-in tube, the first, e.g. annular, cross-section 7 covered in the radial direction, in particular covered around the flow cross-section, e.g. completely covered in the radial direction. An acoustic shield is thus achieved, which provides a return of interfering frequencies, e.g. in the range between 14 kHz and 17 kHz, suppressed in the intake manifold 4, at least significantly reduced.
Zur Erzielung der Abdeckung, welche einer z.B. Überlappung von, insbesondere korrespondierenden, Querschnitten entspricht, weist das erste Ende 18 des Rohrabschnitts 3 z.B. einen Materialquerschnitt bzw. Querschnitt 18a auf, der zur beabsichtigten Abdeckung bei Anordnung am Verdichtergehäuse 2 geeignet ist. Der Querschnitt 18a ist der Form des abzudeckenden ersten Querschnitts 7 z.B. angepasst, ist z.B. ringförmig. Um einen solchen Querschnitt 18a auszubilden, ist das erste Ende 18 des Rohrabschnitts 3, z.B. im zur Anströmseite weisenden Bereich 23, z.B. entsprechend geformt, z.B. verstärkt bzw. gegenüber dem zweiten Ende 19, z.B. verbreitert, z.B. durch Vergrößerung bzw. Erweiterung des Materialquerschnitts der Rohrwandung des Rohrabschitts 3. Dieser Querschnitt 18a des ersten Endes 18 liegt im Falle einer Anordnung an dem Verdichtergehäuse 2 zur Bildung einer erfindungsgemäßen Verdichteranordnung 1 der ersten Einlassöffnung 6 gegenüber und sorgt somit für eine Abdeckung in radialer Richtung. To obtain the cover, which is made of e.g. Overlapping of, in particular corresponding, cross-sections corresponds, the first end 18 of the pipe section 3, for. a material cross-section or cross-section 18 a, which is suitable for the intended cover when arranged on the compressor housing 2. The cross-section 18a is the shape of the first cross-section 7 to be covered, e.g. adapted, is e.g. annular. To form such a cross-section 18a, the first end 18 of the tube section 3, e.g. in the upstream side region 23, e.g. shaped accordingly, e.g. reinforced or opposite the second end 19, e.g. widened, e.g. by enlargement or widening of the material cross section of the pipe wall of the pipe section 3. In the case of an arrangement on the compressor housing 2, this cross section 18a of the first end 18 faces the first inlet opening 6 to form a compressor arrangement 1 according to the invention and thus provides coverage in the radial direction.
Um die Strömungsverhältnisse im Falle einer Anströmung zu begünstigen, ist z.B. der Querschnitt 22 des Innenkanals 21 im Bereich 23 hin zu einer Auslassöffnung 24 bis zu einem zweiten Querschnitt 25 aufgeweitet. In order to favor the flow conditions in the event of an incident flow, e.g. the cross-section 22 of the inner channel 21 widens in the region 23 towards an outlet opening 24 up to a second cross-section 25.
Um die zum Zweck der Kennlinienstabilisierung vorgesehene Luftströmung zu gewährleisten und insbesondere keinen Verschluss der Einlassöffnung 6 zu generieren, ist ein Spalt in axialer Richtung (Anströmrichtung bzw. Richtung der Mittelachse A) zwischen der ersten Einlassöffnung 6 und dem ersten Ende 18 des Rohrabschnitts 3 bei Anordnung des Rohrabschnitts 3 am Verdichtergehäuse 2 vorgesehen. Der Spalt weist zum Beispiel eine Breite von 3mm bis 5mm auf, z.B. zwischen dem ringförmigem Steg 1 1a und dem ersten Ende 18 des Rohrabschnitts 3. Durch den sich aufweitenden Innendurchmesser z.B. im Bereich 23 des Rohrabschnitts 3, wird somit zum Beispiel ein im Schnitt schräg verlaufender Luftkanal (Fig. 2) zwischen dem ersten Ende 18 und der ersten Einlassöffnung 6 geschaffen. Gleichzeitig liegt das erste Ende 18 zur Unterdrückung der Schallrückleitung dem ersten Querschnitt 7 zu diesem Zweck mit dem Querschnitt 18a geeignet gegenüber. In order to ensure the intended for the purpose of the characteristic stabilization air flow and in particular to generate no closure of the inlet opening 6, a gap in the axial direction (flow direction or Direction of the central axis A) between the first inlet port 6 and the first end 18 of the pipe section 3 in the arrangement of the pipe section 3 on the compressor housing 2 is provided. The gap has, for example, a width of 3 mm to 5 mm, for example between the annular web 1a and the first end 18 of the pipe section 3. Due to the widening inner diameter, for example in the region 23 of the pipe section 3, thus, for example, an oblique in section extending air channel (Fig. 2) between the first end 18 and the first inlet opening 6 created. At the same time, the first end 18 for suppressing the return of sound is suitably opposite the first cross section 7 for this purpose with the cross section 18a.
Das erste Ende 18 des Rohrabschnitts 3 ist, zum Beispiel mittels des Bereichs 23, ferner zur Verbindung mit dem Verbindungselement 13, z.B. der Aufnahme 14 in Form z.B. des Ringflansches 15, ausgebildet bzw. vorgesehen. Dazu weist das erste Ende 18 z.B. einen Außendurchmesser 17 auf, welcher zur Herstellung der beabsichtigten Verbindung geeignet ist. Die Verbindung kann von oben beschriebenen Verbindungsarten Gebrauch machen. Zur Verbindung kann das erste Ende 18, z.B. im verstärkten Bereich 23, ein nachgiebiges Element, z.B. ein Andruckelement 23a aufweisen, welches für eine dauerhafte Anordnung bzw. Verbindung sorgt, z.B. durch Reibschluss bzw. Kraft- schluss. Das Andruckelement 23a kann z.B. Abdichteigenschaften ausbilden oder zum Beispiel eine Steckverbindung zwischen Verdichtergehäuse und Rohrabschnitt unterstützen, z.B. klebend unterstützen. The first end 18 of the pipe section 3 is, for example, by means of the region 23, further for connection to the connecting element 13, e.g. the receptacle 14 in the form of e.g. the annular flange 15, formed or provided. For this purpose, the first end 18 has e.g. an outer diameter 17, which is suitable for the preparation of the intended compound. The connection may make use of the types of connection described above. For connection, the first end 18, e.g. in the reinforced area 23, a compliant element, e.g. a pressing element 23a, which ensures a permanent connection, e.g. by frictional connection or force fit. The pressing member 23a may be e.g. Forming sealing properties or support, for example, a connector between the compressor housing and pipe section, e.g. adhesive support.
Ein zweites Ende 19 des z.B. als Steckrohr ausgebildeten Rohrabschnitts 3 ist zum Beispiel wie oben erwähnt zur Verbindung mit einem verdichterseiti- gen Ansaugrohrende 20 z.B. eines Ansaugrohres 4 ausgebildet. Dazu kann z.B. der Außendurchmesser 26 des zweiten Endes 19 dem Innendurchmesser 27 des Ansaugrohrendes 20 angepasst sein. Denkbar ist auch, einen Innendurchmesser des Rohrabschnittes 3 einem Außendurchmesser des Ansaugrohrendes 20 anzupassen. Die Durchmesser 26, 27 sind zum Beispiel so aneinander angepasst bzw. angeglichen, dass sich zwischen den jeweiligen zu verbindenden Enden von Rohrabschnitt 3 und Ansaugrohr 4 eine Klemmkraft infolge einer Verbindung, z.B. Steckverbindung, einstellt, die eine dauerhafte, insbesondere ohne zerstörerischen Eingriff lösbare Verbindung ergibt. Das zweite Ende 19 ist dabei z.B. wie das erste Ende 18 des Rohrabschnitts 3 ebenfalls mit einem Andruckelement 23a an einem Außenumfang versehen, z.B. einem Dichtelement. A second end 19 of the pipe section 3, which is designed, for example, as a plug-in pipe, is formed, for example, as described above, for connection to a compressor-side intake pipe end 20, for example, of an intake pipe 4. For this purpose, for example, the outer diameter 26 of the second end 19 can be adapted to the inner diameter 27 of the intake pipe end 20. It is also conceivable to adapt an inner diameter of the pipe section 3 to an outer diameter of the intake pipe end 20. The diameters 26, 27 are, for example, adapted or adapted to one another such that between the respective ends of the pipe section 3 and intake pipe 4 to be joined, a clamping force due to a connection, eg plug-in connection, sets in, providing a permanent connection, in particular without destructive interference results. The second end 19 is, for example, as the first end 18 of the pipe section 3 also provided with a pressure element 23a on an outer periphery, for example a sealing element.
Zur Herstellung der erfindungsgemäßen Verdichteranordnung 1 wird zum Beispiel ein Rohrabschnitt 3 mit einem Verbindungselement 13 bzw. einer Aufnahme 14 des Verdichtergehäuses 2 verbunden, insbesondere durch Stecken verbunden, z.B. durch Steckverbinden des ersten Endes 18 des Rohrabschnitts 3 mit dem Ringflansch 15 des Verdichtergehäuses 2 infolge eines Zusammenführens in axialer Richtung. In einem weiteren Schritt wird zum Beispiel das zweite Ende 19 des Rohrabschnitts 3 mit einem verdichterseitigen Ende 20 eines Ansaugrohres 4 verbunden, insbesondere steckverbunden, z.B. ebenfalls durch Zusammenführen in axialer Richtung. To produce the compressor arrangement 1 according to the invention, for example, a pipe section 3 is connected to a connecting element 13 or a receptacle 14 of the compressor housing 2, in particular connected by plugging, e.g. by plugging the first end 18 of the pipe section 3 with the annular flange 15 of the compressor housing 2 due to a Zusammenführens in the axial direction. In a further step, for example, the second end 19 of the pipe section 3 is connected to a compressor-side end 20 of an intake pipe 4, in particular plug-connected, e.g. also by merging in the axial direction.
Bei einer erfindungsgemäßen Brennkraftmaschine, z.B. einem V-Motor mit erster und zweiter Zylinderbank (Dieselmotor, Benzinmotor, etc.), welche eine erfindungsgemäße Verdichteranordnung 1 aufweist, ist die Verdichteranordung 1 z.B. zur Förderung und Verdichtung von Frischluft angeordnet. Ein in dem Verdichtergehäuse 2 angeordnetes Verdichterrad ist dabei z.B. zum Zwecke einer Motoraufladung von einem damit verbundenen Turbinenrad eines Turboladers antreibbar angeordnet. Somit ist Frischluft (Ladeluft) infolge einer durch das Turbinenrad veranlassten Drehung des Verdichterrads auf bekannte Weise an eine Brennkammer eines Zylinders bzw. einer Zylinderbank der Brennkraftmaschine über einen Verdichterauslass förderbar. In an internal combustion engine according to the invention, e.g. a V-type engine with first and second cylinder bank (diesel engine, gasoline engine, etc.) having a compressor arrangement 1 according to the invention, the compressor arrangement 1 is e.g. arranged for the promotion and compression of fresh air. A compressor wheel disposed in the compressor housing 2 is e.g. arranged to be driven by an associated turbine wheel of a turbocharger for the purpose of engine charging. Thus, fresh air (charge air) due to a rotation of the compressor wheel caused by the turbine wheel in a known manner to a combustion chamber of a cylinder or a cylinder bank of the internal combustion engine via a compressor outlet can be conveyed.
